title: N'-[(E)-2-Hy-droxy-5-meth-oxy-benzyl-idene]pyridine-4-carbohydrazide monohydrate.
abstract: The title compound, C14H13N3O3·H2O, adopts an E conformation with respect to the azomethine bond and crystallizes in the amide form. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, the lattice water molecule plays a major role in the supramolecular architecture by interconnecting adjacent molecules into a three-dimensional netwrok by means of O-H⋯O, O-H⋯N and N-H⋯O hydrogen-bonding inter-actions. The structure also features two non-classical C-H⋯O inter-actions.
